adi,tmc2209

Description

Analog Devices TMC2209 stepper motor driver.

Example:
tmc2209: tmc2209 {
    compatible = "adi,tmc2209";
    enable-gpios = <&gpio0 0 GPIO_ACTIVE_HIGH>;
    m0-gpios = <&gpio0 1 GPIO_ACTIVE_HIGH>;
    m1-gpios = <&gpio0 2 GPIO_ACTIVE_HIGH>;
}

Properties

Node specific properties

Properties not inherited from the base binding file.

Name	Type	Details
`step-width-ns`	`int`	Minimum pulse width in nanoseconds for the step signal. Default value: `100`
`m0-gpios`	`phandle-array`	Microstep configuration pin MS1.
`m1-gpios`	`phandle-array`	Microstep configuration pin MS2.
`dual-edge-step`	`boolean`	If present, the stepper motor controller supports dual edge step signals. This means that the step signal can be toggled on both the rising and falling edge.
`micro-step-res`	`int`	micro-step resolution to be set while initializing the device driver. Default value: `1` Legal values: `1`, `2`, `4`, `8`, `16`, `32`, `64`, `128`, `256`
`en-gpios`	`phandle-array`	GPIO pins used to control the enable signal of the motor driver.
